A single-phase transformer is rated at 10KVA, 220/110V.
a. Compute the rated current of each winding.
b. If a 2Ω load resistance is connected across the 110V winding, what are the currents in the high-voltage and low-voltage windings?
c. What is the equivalent load resistance referred to the 220V side?
Three light bulbs are connected in series to a 100-V battery in a circuit. Each light bulb dissipates 30W, 40W, and 50W, Respectively. Find the current (I) through the light bulbs.
Desing a logic Circuit that receives an array X(4 bits:X1,X2,X3, and X4) and makes it available as an output O(4 bits: O1,O2,O3, and O4) after one clock delay, subject to the control of input signals : "a" and "b". If a=b=0, then the data is NOT t..
Resistors of R1= 10Ω, R2 = 4Ω and R3 = 8Ω are connected up to two batteries (of negligible resistance) as shown. Find the current through each resistor.
An analog cellular system has 250 duplex channels available (250 channels in each direction). To obtain acceptable transmission quality, the relation between reuse distance (D) and cell radius (R) has to be at least D/R = 7. The cell structure is d..
